Question

I need help, none i can't seem to find a solution to my problem.

I'm trying to create a directory in FTP Server:

Dim request As FtpWebRequest = FtpWebRequest.Create("ftp:\\*******")
        Dim creds As NetworkCredential = New NetworkCredential("****", "*****")
        request.Credentials = creds
        request.KeepAlive = True
        request.EnableSsl = True
        request.UsePassive = True

        request.Timeout = 10000000
        request.ReadWriteTimeout = 10000000
        ServicePointManager.ServerCertificateValidationCallback = New System.Net.Security.RemoteCertificateValidationCallback(AddressOf customCertValidation)

        Dim resp As FtpWebResponse = Nothing
        request.Method = WebRequestMethods.Ftp.ListDirectoryDetails

        Using resp
            resp = request.GetResponse()
            Dim sr As StreamReader = New StreamReader(resp.GetResponseStream(), System.Text.Encoding.ASCII)
            Dim s As String = sr.ReadToEnd()
            If Not s.Contains("newfolder") Then

                request = FtpWebRequest.Create("ftp:\\********")
                request.Credentials = creds
                request.Method = WebRequestMethods.Ftp.MakeDirectory
                resp = request.GetResponse()
                Console.WriteLine(resp.StatusCode & "Created")
            Else
                Console.WriteLine("Directory already exists")
            End If
        End Using
    Catch ex As Exception
        Console.WriteLine(ex.ToString)
    End Try

Function for customCertValidation

Function customCertValidation(ByVal sender As Object,
                                            ByVal cert As X509Certificate,
                                            ByVal chain As X509Chain,
                                            ByVal errors As SslPolicyErrors) As Boolean
    Return True
End Function

I get the following error:

I have tried everything on the web but nothing seems to work, can someone please tell me what is wrong. Thank You
